Thanks for your answer.
I have seen this line in the response headers of the second request of the website ( first one is for a redirecting to https):

On the response headers of the following request for a CSS file I read:

Here the test I run: http://www.webpagetest.org/result/180426_J3_19c55867658f5edc7e7f842fabcabd00/2/details/#step1_request2
Well I am not at all a caching expert, I see no X-Litespeed-Cache:hit however. So I wanted to ask you if you could evtl help me further please of what could I tell to the hoster exactly? Any link to a documentation of your Wiki for that evtl please?
I have a subscritpion of a cloud hosting at TMDHositng, no VPS. Also note that nameservers are the ones of Cloudflare that I use if this is of importance to know here.
Kind regards and really appreciate
Julien
